A snowmobile triggered a large avalanche Tuesday afternoon east of Alta Ski Resort, but no one was caught or buried.
Craig Gordon, a forecaster with the Utah Avalanche Center said another forecaster, Brett Kobernik, was in the vicinity when the slide occurred.
"Nobody was caught or buried or injured," Gordon said.
The avalanche was in Dry Fork, east of Little Cottonwood Canyon and outside the bounds of Alta Ski Resort, he said.
The slide was 3 feet deep and 300 feet wide and began on an east-facing slope at an elevation of 10,400 feet, according to a tweet from Kobernik at about 1:45 p.m.
